Upload firmware to printer innormal mode - dont put printer in Program Update mode.
The uploading process will stuck at 70-80% - it is ok!
Open task manager and stop updater process.
Printer will blink for about 5-15 minutes - then will power OFF.

Now power on the printer - chipless firmware is installed now in your printer!
